2 Claims. (Cl. 25-131) This invention relates to wall forms, and more particularly to bucks, or forms, for creating openings for windows in walls cast with concrete or the like.

The primary object of this invention is to provide a novel and improved buck for casting a wall of concrete or the like, with window frames in place.

Another object is to provide apparatus consisting of two similar half bucks, between which a window frame is held snug and firmly while concrete is poured around them in the formation of a wall.

Another object is to provide such a buck that can be used to locate a window frame and form an opening therefor, any place in a concrete wall form, either at, below, or partially above grade.

Still another object is to provide a buck composed of two similar and separable halves that may be individually fitted to a wall form, with a window frame sandwiched in between, by a single workman, without requiring temporary or make-shift auxiliary locating aid.

A further object is to provide buck apparatus made up of similar paired halves that may be combined with a second paired set of buck halves of different thickness to form Window openings in walls of three different thicknesses.

Other objects are to provide a buck of the type stated that is relatively inexpensive to manufacture, rugged in construction and indefinitely re-usable.

These and other objects of the invention will become apparent from a reading of the following specification and claims, together with the accompanying drawings, wherein like parts are referred to and indicated by like reference characters and wherein:

Figure 1 is a perspective elevational view of the assembled window buck that is the subject of this invention, showing it mounted on the inside face of the outer wall form; t

Figure 2 is an inside, or rear, elevational view of one of the half-buck, or mold members, in its unmounted and unassembled condition;

Figure 3 is a perspective view of one of the half-bucks as it appears when mounted below grade, or on the inside face of the outer wall form for a concrete foundation wall, with a window frame positioned thereon;

Figure 6 is a vertical sectional view taken along the line and in the direction of the arrows 6-6 of the Figure 4; I

States Patent 0 Figure 7 is a left end view of the mold member il1us-* trated in the Figure 8; and

Figure 8 is a top plan View of the same. Referring more particularly to the drawings, there is seen in the Figure 5 an exploded view of the window buck assembly that is the subject of this invention. Each buck is made up of two similar and mating half buck, or

mold members, broadly indicated by reference numerals 10 and 11. These mold members, when properly fitted and locked together, hold the window frame, broadly indicated by reference numeral 36, therebetween, while a concrete wall is being poured. Each half buck 10 and 11 may be fabricated from any suitable material having the required physical qualities of rigidity and strength. In their preferred form, they are made from 10-gauge steel strip suitably cut, shaped and welded together. -Inasmuch as both mold members 10 and 11 are identical in construction, all of their elements have been given the same reference numerals and the description of either mold member In or 11 applies to the other also.

Each mold member 10 or 11 has top, bottom and-side walls 12, 15, 13 and 14 respectively, defining a closure open to the front and rear. The overall shape of t the mold members is substantially rectangular, and of a size to accommodate the window frame 36, with which it is to be used. The cross-sectional shape of the mold members determines the outside and inside edge of the window opening to be formed. The top wall 12 lies at a right angle to the side walls and the wall form and shapes the lintel of the window opening. The side walls 13 and 14 taper sideward and outward to form the side walls of the opening, while the bottom wall 15 is tapered downward and outward to form the window sill, as shown in Figure 6. Since the two mold members are positioned inside to inside, each shapes one-half of the window opening with window frame 36 positioned at the center-line of the opening, in the case where two mold members of equal thickness are used.

A plate 23 is positioned at the rear edges of the top and bottom walls 12 and 15, respectively, of the mold. A bracket 22 is also positioned at the rear edges of the top and bottom walls 12 and 15, across the back face of the mold, spaced from the plate 23.

Reference numeral 25 indicates a slot in the plate 23 through which the flat locating bar 26 is mounted.

Reference numeral 24 indicates a rearwardly faced female locating slot through the bracket 22. The locating slot 24 is aligned with the locating bar 26 and is of a size and shape corresponding to the cross-sectional configuration of the locating bar 26.

Reference numerals 19 and 20 indicate two spaced nailing strips positioned at the front edges of the top and bottom walls 12 and 15, respectively, and extending across the front face of the mold. The nailing strips 19 and 26) are positioned out of alignment with the locating bar and the bracket slot 24, as is seen -most clearly in Figure 2. Eachof the nailing strips 19 and 20 have,

locating holes 21 therethrough to receive nails 35 used to attach the mold to the wall form upon which it is to bev male locating slot 24 of the bracket 22 of its mating mold A transverse bore 27 is positioned proximate member. the free end of the bar 26. A wedge, or lockingkey, 28

Fatented Apr. 9, 1951v 3 is attached to the bracket 22 by means of a flexible chain or cable 29.

Reference numerals 16, 17 and 18 indicate locating flanges for the window frame 36 which are positioned at the inside edges of the top and side walls 12, 13 and 14, respectively.

The creation of a window opening and the mounting of a window frame therein, in a poured concrete wall, is brought about by the'following procedure:

Referring to Figure 3, there is seen the inside face of a plywood panel form 30 that will eventually form the outside face of a poured concrete wall. The wall form is shown as being of plywood construction, although it is to be understood that any other suitable sheet material may be used. Reference numeral 34 indicatesa reinforcing strip along the top edge of the form.

The mold member is placed against the form 30 with its top wall 12 located along the line of the top of the intended'window opening. As shown in the drawings, the window opening will be below grade, that is below the top edge of the completed wall, although it is to be understood that it might be placed at grade or partially above grade, if so desired.

The so positioned mold member 10 is hung in place on the form 30 by means of nails 35 which are driven through the holes 21 in the nailing strips 19 and 29, and into the form 30. Then the window frame 36 is positioned on the inside face of the mold member 10, over the locating flanges 16, 17 and 18, as is shown most clearly in Figure 5. The window frame illustrated is fabricated from sheet metal, and has slots 38 in the end walls thereof in which the window sash, not shown, is pivotally and slidably mounted. Reference numeral 37 indicates end fins which extend into the wall cavity and serve to anchor the frame 36 in place in the poured concrete. The convolutions of the sealing seat between the frame and sash also serve to receive concrete and aid in further anchoring the frame 36, as is seen most clearly in Figures 4 and 6.

With the frame 36 positioned on the mold form 10, it will be noted that the locator bar, or male element 26, extends through and beyond the window frame. The other half of the buck, which is similar in structure, namely mold member 11, is then caused to mate with mold'membcr 10 with the window frame 36 sandwiched thercbetween, as seen in Figure 1. The flanges 16, 17 and 18 of mold member 11 being fitted into the window frame opening on what will be the inside of the frame, as seen in Figures 4 and 6. At the same time the locator bar, or male element, of mold member 10 is fitted through the locator slot, or female element 24 of mold member 11, and the locator bar 26 of the mold member 11 similarly fitted through the mating locator slot 24 of mold member 10. When so positioned, the transverse bores 27 of each locator-bar 26 will be positioned at the outside edge of the slots 24. The tapered wedges are then passed through the bores 27 and tapped home, which causes the locator-bars to be pulled through the locator slots 24, causing the two buck members 10 and 11 to be drawn tightly together, in positive aligned opposition, against both faces of the window frame 36.

The so assembled buck and held window frame will appear, as in Figure l, suspended from the wall form 30. A second wall form 31, having a re-inforcing strip 33 at its upper edge is then placed against the outer face of the mold member 11, as seen in Figures 4 and 6. The two wall form sheets 30 and 31 are joined together by means of tie-rods, not shown, to form a wall cavity containing the buck assembly there-between.

The wall cavity is then'filled with concrete 32. The filled form will then have the appearance of the structure shown in Figures 4 and 6. After the concrete has set, the wall forms 30 and 31 are stripped away. The wedges Z8 are knocked out, thereby releasing the lock-bars 26. The mold forms 10 and If are easily pulled out of the cavity which they define, by one man, leaving a window opening in the concrete wall containing the window frame 36 firmly imbedded in the concrete. Due to the straight edge of the top wall 12, and the angular disposition of the side and bottom walls of the half-bucks, the mold members are easily removed from their positions by a simple straight pull on the nailing strips 19 and 20. No tilting or bending of the forms is required. Thus our buck is not limited to grade positions, but may be placed anywhere in a wall or partially above the wall.

Inasmuch as the mold members 10 and 11 are identical in structure, a builder having a number of such members may easily store and re-use them in any sequence; since there is no problem of keeping inside or outside, or right and left hand members separated. For the same reason, molds of different 'cross sectional thickness may be combined to form window openings in walls of different thicknesses. For example: In the case of the buck illustrated herein, the mold members 10 and 11 are 2 /4 thick, and when used with a window frame 2 /2" thick provide a form for use in an 8 inch poured concrete wall. A second set of paired mold members 4%" thick will provide-a window opening for a 12 inch wall; while by combining one moldmember from the 2 /4" set with one from the 4% inch set a wall thickness of 10 inches is obtained. Thus the builder is required to stock only two sizes of mold members to be able to combine them to fit three different wall thicknesses. This results in a substantial saving in both-capital investment and warehousing space. 4

It will now be clear that there has been provided a device which accomplishes the objectives heretofore set forth.

While the invention has been disclosed in its preferred form, it is to be understood that the specific embodiment thereof as described and illustrated herein is not to be considered in a limited sense, as there may be other forms or modifications of the invention which should also be construed to come within the scope of the appended claims.
